3,865 financial reports of public companies (about 65% of the total) all of which pass 100% of the fundamental accounting concept validation cross checks. (The prior version had 3,015 companies or about 50%)

Synchronized all the validation rules to the commercially available versions provided (99.9% consistent)

Changed the "IF...THEN" rules which were hard to edit/maintain to immediate IF functions per the suggestion of some. This was REALLY helpful. This change makes maintenance significantly easier.

I really cannot overstate the usefulness of these Excel spreadsheets. What I have stumpbled across is the fact that the same business rules that I use to validate an XBRL-based financial report can be used to extract information from reports. Today, each data aggregator that extracts information from reports had to create their own set of algorithms and rules for doing so.
